I'm also wondering about adding something like the following summary of 
features with odd transactional behaviour. I'm sure there's more than 
I've listed, but nothing is jumping out at me.

     Exceptions to normal transactional rules
       Some PostgreSQL features, functions and data types differ from the    usual transactional behaviour described in this chapter. Differences    are generally mentioned in the documentation sections for the    features they affect. Such exceptions are collected here for    easy reference.   
                  Serial pseudo-types                         SEQUENCEs -                         Advisory locks -                         Disk I/O to files outside the database, as performed by      COPY ... TO, adminpack functions, and other      add-ons. See ,      .
